Align Antenna
After the OAP180 unit is mounted, connected, and the radios are operating, the
antennas must be accurately aligned to ensure optimum performance of the OAP180
links. In this point-to-multipoint configuration all OAP180 nodes must be aligned with
the root OAP180 antenna.
Check the OAP180 for Activity
Check the OAP180 LEDs for activity. Four of the eight LEDs on the bottom of the
OAP180 indicate activity; four LEDs are not used at this time. Check the four active
LEDs to determine if the AP is working.
The grey LEDs in the illustration are not currently used. The following chart explains
the meanings for the remaining LEDs.
LEDs Function

When power is applied to the system this LED initially turns amber, then blinks green when
the system power check is applied, and then is a steady green when power is on.
Ethernet
Link
The Ethernet Link LED blinks green when a link has been detected and is in use.
Radio 1
